DC Injection Braking System

Image
 DC Injection braking is a method used to rapidly decelerate and stop the rotor of AC induction motors without using friction.  Application And principle Of Operation. A typical application of this is in the tripper car conveyor system above, the tripper car is driven by direct-drive motors coupled to the tripper wheels. The car can move freely(forward and backward) on the rail and the car is stopped at precise locations to discharge product. The image below would give you a clearer understanding. We don't want a situation where we stop the electric motors but the car continues to roll. This is undesirable because you would struggle to stop the tripper car at the exact point where you want to discharge the products. It could also create a dangerous situation where you stop the car but, the moment of inertia could roll the car until it hits the mechanical stoppers at the end of the rail, potentially derailing the car. Electronic brakes are desired due to the fact that they have no m
